Procedure 2-12 Nozzle Reinforcement

The following are only guidelines based on Section VIII, Division 1 of the ASME Code [1]. This is not an attempt to cover every possibility nor is it to become a substitute for using the Code. 

It is advisable but not mandatory for reinforcing pad material to be the same as the vessel material [1, Section UG-41]  

While minimum thicknesses are given in Reference 1, Section UG-16(b), it is recommended that pads be not less than 75% nor more than 150% of the part to which they are attaehed. 

While no minimum is stated, it is reeommended that re-pads be at least 2 in. wide. 

Reinforcing pads should be formed as closely to the contour of the vessel as possible. While normally put on the outside of the vessel, re-pads can also be put inside providing they do not interfere with the vessel s operation [1, Section UG-82].
